WATER-HEATING APFABATUS.

Application filed September This invention relates to water heaters and more particularly to the class wherein liquid fuel burners are employed; and it has for its general objects to provide a water'heater of extremely high thermal efficiency; to provide a water heater of the coil type that is compact and very rigid and is practicallyfindestruotible; to provide a water heater of the aforesaid class that requires little attention, is easy to take care of, wherein both the burner and the water circulating unit are readily accessible for the purpose of cleaning,'that is self-contained, comprising, as it does, a base incorporating a burner and fuel supply, and a water circulating unit supported inoperative relation to the burner, all of which are secured together so that the assembly may be conveniently transported from place to place as a single structure wit :wsurance that all parts willbe maintained in proper relation to each other; to provide the base of the structure with legs which may be adjusted to compensate for irregularities in the floor or other supportingsurfacewhereon the apparatus stands as well as to adapt it to slight differences in pipe lengths when the apparatus is being installed thereby'to avoid such extreme accuracy in pipe fitting as would otherwise be necessary; and to pro-' tion of the invention by, the use of reference vide a water heater of the foregoing charac ter that is particularly convenient of assem bly and installation.

To the attainment of these ends, with other and more specific objects which will hereinafter appear, our invention in its present preferred form i'nay be defined briefly as consisting of-a stand or base incorporating a burner and liquid fuel supply means in communicative connection with the burner and to wiich base or stand is secured, directly above the burner, a water receiving manifold from which a tubular column risesthat is surrounded by a plurality of coils which have connection at their lower ends with said inlet manifoldand at their upper ends with an outlet manifold that is secured to a cap, rigidly connected to the upper end of the column; and a suitable casing surrounds the water receiving manifold and is permanent- .ly carried by the stand or base and supports a removable drum which is preferably'constructed with a double wall and which extends from said casing to the cap and encloses the coils.

be understood that we do not limit ourselves to thestructural details thereof further than is required by the terms of the claims annexed hereto.

In the drawings, Fig. 1 is a front elevation of our improved water heater; Figs. 2 and'Q (on the respective sheets 2 and 3), when matched on the lines aa-, constitute a central vertical section through the apparatus ina plane parallel tothat of Fig. 1'; Fig.3 is a'horizontal section through the upper end of the apparatus as indicated by the line 3 3 of Fig. 2; Fig. 4 is a section substantially on the lines 4ll of Figs. land 2; Fig. 5 is a horizontal section through. the stand or base, as indicated by the lines of Figs. 1 and 2, the position'of the burner being indicated by dot-and-dash lines;,Fig. 6 is a vertical section through one of the legs of the base or stand, as indicated by the characters, 1 designates a water receiving unit or manifold which is in the form of a hollow annulus having radially disposed outwardly extending heat abstracting fins 2, and similar inwardly extending fins 3. the atter connecting at' their inner ends with an in- The unit or manifold 1 is disposed ears6 which extend outwardly and bear upon the inturned upper ends 7 of metal straps 8 which are secured by bolts 9 to the inner sides of legs 10. The cars 6 are shown as secured to the ends 7 of the straps 8 by bolts 11. The legs 10 are of channelformati'on, and the bolts 9 extend through slots 12 therein so that the legs may be individually adjusted to compensate for irregularities in the floor or other supportingsurface whereon the apparatus stands, as well as to enable the entire structure to be raised and lowered within a reasonable range of adjustment to adapt it during installation to uncertain pipe lengths. I

The skirt 15 of an annular shell 16 is legs pass throunh apertures in the skirt.

' short rear panel 18 are also clamped between the last mentioned elements, certain of the bolts 9 passing through the edge portions of the panels to lock them in place. The side panels 1? .teri'ninate at their upper ends a suitable distance below the plane oft-he lower end of the 15 and have their lower edges turned inwardly to provide flanges 20. The rear panel 18 is formed adjacent its lower edge to effect an abutment 21 in the plane of flanges 20. Asuitable trap 22 is adapted to be supported, through its ledges 23, from the flanges 2O whereon it is properly positioned by engagement at its rear edge with the abut" ment 21. The top edge of the rear panel 18 is deflected rearwardly at a suitable angle to form a rest 24 for the burner drum, shall presently appear. A fuel supply pipe 25 e2ztends through apertures in the side panels 17, located near their lower rear corners, and the pipe is secured to said panels by suitable clamps 26 that are connected by bolts 27 to ledges 28 that extend inwardly from said panels. Supported by and between the front portions of the side panels 17 in substantially the horizontal'plane of the pipe 25 is a bar 30. A liquid fuel burner 81 is supported its front side from the bar 30 through a suitable leg 32, and at its rear side from the fuel supply pipe by an elbow fitting 33 through which the burner is communicatively connected to said pipe. The present burner is of the well-known tubular type and is equipped with a wick that may be raised and lowered by means of the wicl; raising spindle 235.

A. fuel tank or reservoir is shown as situated on each side of the stand or base. The reservoirs are of the well known gravity-feed liquid seal type. Each is adapted to be inverted over a fuel distributing receptacle which may contain su'llicient fuel to cover the mouth or discharge opening of the reservoir and thus prevent the How of additional fuel from the reservoir until the supply within the distributing receptacle is so depleted as momentarily drop below the mouth of the reservoir. The distributing receptacle associated with each of the reservoirs is desig nated 41 and it has connection with tie adjacent end of the fuel supply pipe 25. To assist the supply pipe in supporting the dis tributing receptacles and reservoirs, brackets 42 are provided which rigidly connect the upper ends of the distributing receptacles to skirt the adjacent panels 17. Although it convoirs 40 are contained in carriers 44 which are hinge'dly connected at 45 to the distributing receptacles 41 and may be swung from the position shown in the drawings to an inverted position in front of the distributing receptacles, thereby to swing the reservoirs to an u right position. The carriers 40 are sustained in proper inverted position by the engagement of brackets 46, which are carried by their free ends, with stops 4? which are secured to the lower ends of ie sidepanels 17 and entend outwardly and forwardly therefrom. I

Returning to the burner 31, the same is provided with a fine or drum which is supported above the burner in such manner as to be capable of being swung rearwardly to expose the top of the burner for the purposes lighting, cleaning and removingthe wick, drum when tilted rearwardly bearing upon the rest 24 provided bytli'e rearwardly turned upper edge portion of the rear panel 18. The nature of the connection between the fine or drum 50 and the burner 31- forms no part of the present invention andtherefore it is deemed unnecessary to specifically describe it in this connection although it may be generally related that the'conne'ction is such that the drum-may be lifted from the burner or, when resting upon the burner and assuming as it does a hinge connection tliere' with, tilted rearwardly to bear upon the rest 24 as above described. For a more detailed explanation ofthis feature, reference may be had to the copending applicationof Lee S. Chadwick, Serial No. 539,079, filed February 25, 1922.

Fitted within and fastened to the ring 4 of the water receiving unit or manifold l-is the lower end of a tubular column 55, and a flanged collar 56 is applied to its upper end.

A plate 57, which r upon the flange of the collar 56, closes the top of the column, and screws 58, which pass through registering apertures in the collar and the plates 57 are threaded into bosses 60 which depend from a cap 61.

A water outlet unit or manifold 65 has its upper end passed through an aperture in the cap (31 and is rigidly secured to the cap by bolts 66 which pass through ears 6'? of said unit orinanifold and through hollow bosses 68 of the cap. Three coiled tubes, preferably copper, encircle the column 55 and establish communication between the water receiving unit or manifold 1 and the outlet unit or manifold 65. The coiled tubes are designated 70, 71 and 72, and their lower ends are shown as connected, as by unions 73, to outlet connections of the unit or manifold 1, while their upper ends are connected, as by unions 74, with inlet connections ofthe unit 1,7os,17s" Y Y 3 or manifold 65. ;Attention is called particularly to the arrangement of the coils. In Fig. 2 it will be observed that tube is adjacent the column 55 and a tube 72 is spaced a mathem in the relation described we utilize a staple 75 of comparatively stiff wire the branches whereof pass through diametrically opposite pairsof holes in the column 55 and at one end embrace portions of t tubes 70 and 72, and at the othera portion of the tube 71. This staple forms a support for the central portion of all of the tubes and at their ends the tubes areheld rigid by their. connection with the respective units or manifolds 1 and 65.

A cylindrical drum 8O encloses the coiled tubes and its somewhat contracted lower end 81 fits within the upper end of the base shell 16, while its upper end is contracted and fits about the edge portion of the cap 61. The drum is supported by a shoulder 83 which rests upon the shell 16. The drum is preferably of double wall construction, the inner wall being designated 84. The lower end of the inner wall is flanged outwardly, as indicated at '85, and rests upon an inwardly directed bead 86 of the drum and its upper end fits within a contracted collar 87that is attached to the top of the drum, as by a seam 87. Air is admitted to the space between the inner and outer walls through apertures 88 adjacent the lower end of the drum and escapes into the interior of the drum adjacent its upper end through holes 89 that are formed in the inner wall 84. The cap 61 is provided with a vent opening 90 shown as surrounded by a collar 91 to which a suitable flue may be connected if desired. A water inlet pipe 95 is extended through an aperture in the skirt 15 of the base shell 16 and is threaded into a boss 96 of thewater receiving unit or manifold 1; and an outlet pipe 97 is threaded into the upper end of the outlet unit or manifold 65.

WVhen the burner is lighted, a part of the products of combustion rise up and about the hollow annulus of the receiving unit or manifold 1 and the remainder pass upward into the column 55. Much of the heat of the products which pass about the annulus of the unit or manifold 1 is transmitted through the wall thereof to the water contained within the annulus, and to said wall through the heat abstracting fins 2 and 3, and raise the temperature of the water within the manifold or unit. The products continuing up- The tubes are naturally somewhat resilient and to asslst in-inaintainmg,

ile

ward impinge against the coiled tubes 7 O, 71 and 72 and said tubes, arranged as hereinbefore described, constitute baffles which cause the products to progress upwardly through a tortuous course so that their ascent will be prolonged suflicientlyto enable them to expend the maximum of their thernial value in heating the water within the tubes. The products which pass directly into the column 55 escape through apertures 99 that are situatedncar thelower end of the column and join those which pass upwardly about the annular portion of the unit 1 or manifold '1, thus raising the temperature within the upper portion of the drum and con sequent-1y increasing the efliciency of the 'ap paratus; The reason for locating the apertures, 99 near the lower end of the column55 is to preserve the products of higher thermal value which rise directly within the column for heating the upper ends of the tubes 70, 71

and 72 as otherwise the upper ends of said tubes would beceprived of products of very high temperature due to the fact that much of the heat is abstracted from the products as they pass about the water inlet manifold.

Also, the gases within the upper end of the drum are protected from the cooling influences of the surrounding outside air by the body of comparatively warm -air passing upward through the space between the innerv and outer walls of the drum, said air becoming heated by radiation from the inner wall ficient water heatergthe construction whereof very rigid, it being noted that the unit or manifold 1 securely fastened to the sup porting legs 10; t-hatthe column 55, which is surmounted by the cap 61, fixed to the unit or manifold 1; that the coiled tubes are firm 1y secured at ,both'ends by sohlerless oints iii the nature of clamping iinioneto the suhstantial structure made up of the unit or manifold 1, column 55, cap 61 and unit or manifold 65 and that the burner an d fuel supply means are incorporated in a very substantial manner wick, it is only necessary to tilt the drum or flue 5O rearwardly when-the wick will beeX- posed; andto clean the Water circulating tubes, the drum 80 may be lifted above the cap 61.

By having two reservoirs 40, not only may the z'rpparatus be kept supplied with an emple amount of fuel at all times, but one the reservoirs will empty before the other starts to discharge owing to theobvious fact that a Very slight difference in the elevation of two reservoirs would 0 cause th diseua mouth of one of them to remain covered the quantity of fuel in the corresponding (T tributing receptacle unt l the suppl other reservoir was cnlirev orzhe that when one of the reservoirs has on, it may be refilled or replaced by a full reservoir at the convenience of the us and ll uring the time that it is empty or while it is being refilled or changed the othc will supply fuel to the burner.

Another feature to which especially directed is the so-called *rc-um design of the water receiving ui ild or unit 1. It will be observed that in en s tion it has a rounded bottom and upwardl converging side walls which come very clos together at their upper ends. The prodi of combustion impinge age and sweep up along the side walls and come together tliereabove, entirely enveloping unit and avoiding a body of inactive air for in in'ir iediately above the unit as is the case with elements of prevailing cross-sec shapes.
